PRISON.

' SPECIFICATION forming part of Iietters Patent No. 424,936, dated April 1, 1890.

Application filed August 29, 1889. Serial No. 322,372. (No model.)

To all whom t may concern:

Be it known that I, CHARLES SCHOENFELD, a citizen of the United States, and a resident of Canton, county of Stark, State of Ohio, have invented a new and useful Improvement in Prisons, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, making partof this specification.

tion of a prison, illustrating my invention.

Fig. 2 is a view of an upper corner, also showing section on line 5c 0c, Fig. 1. Fig. 3 is a view in perspective of a perforated panel-plate. Fig. 4t is a vertical sectional view showing detail, full size. Fig. 5 is a horizontal sectional vieW showing detail of construction, full size. Fig. 6 is a vertical sectional view of modified form of construction, showing the body of the prison formed to receive the perforated plates and to which the plates are directly secured; and Fig. 7 is a fragment of perforated panel-plate.

Similar letters of reference will indicate corresponding parts in all of the figures of the drawings.

I-Ieretofore prisons of' this class have been constructed of solid plates of metal and crossbars of metal riveted together to form a lattice through which light and air is provided for the comfortf and health 'of the occupants of the prison, the overlapping bars referred to necessitating the use of an increased amount of material as well as labor in punching and riveting the bars together, both of which operations were not only expensive but unsatisfactory, in this, that the strength of the bars was greatly reduced by the frequent perforations for the rivets by which they were secured together, and, finally, the structure was limited in strength to the strength of the rivet. Thus after a magni- Well-known ways.

tude of show a very unsatisfactory result was achieved, for by the use of an ordinary crowbar placed in the apertures of the lattice that part of the structure could be torn apart and the object of the structure defeated.

The object of this invention is to provide a prison having all of the advantages of the structure hereinbefore referred to so far as related to providing light and air, and'in addition thereto additional strength and security.

For the purpose of this application I have shown the body of the prison, including the floor and ceiling of the corridors, to be made of solid metal plates A B C. Said plates may be wholly of iron or of steel, or the plates made of alternate layers of iron and steel Welded together; but the essential feature of this invention consists in providing in a prison structure a Wrought-metal perforated plate D, as shown in Fig. 3, which plate is used in the construction of the cell, corridor, and

doors, either in Whole or in part, as well as in the panels E F, in the place of lattice-work formed by cross-bars in any of the usual and The said plate D may be formed of any suitable metal, preferably iron or steel, or V of alternate sheets of iron and steel Welded togetherl and rolled into sheets of desired thickness, forminga sheet of alternate layers of iron and steel. For the purpose of this case I have shown in the construction sheets of metal composed of layers of iron and steel, the two outside and the central layers a of iron, and the remaining two b of steel.

In construction the plates for the panels E or doors F are provided of 'such size and form as maybe required. Theperforations d may be of any desired form or size, as their only service is to admit air and light to the interior of the prison. The perforations may be made in any of the usual Ways of punching by the use of a suitable die and punch operated by a press of such power as may be required. As the operation of punching is liable to slightly enlarge the plates, the sizing of them should be deferred until after that operaa tion has been completed.

In the construction ot' doors metal stiles f roo maybe used to stiften and strengthen the edge portion of the door. Said stiles or frames may be of any desired width, form, or ornamentation; but for the purposes of this application I have chosen a plain liat bar, the same as shown and used for the door-facings h, and in this case the same form of metal stile is used about the panels F.

To secure the plates A, B, C, and D in position to form a prison, as shown in Fig. l, angle-irons, as G and II, are provided, between the flanges of which the ceiling and side portions B, D, and A are secured by rivets, as shown in Fig. 2,the Ilangesj` embracing the edge of the plate B, and the flanges l m enibracing the plate D. Similar angle-irons G and Il are also used to secure the floor portion C to the side panels A and D, the floor C being' secured between the flanges n 0, as shown in vertical section, Fig. et; and similar angle-bars are used vertically at the corners N, by which the plates are secured in position.

In Fig. G is shown a vertical sectional View through the upper corner of a modification of construction, in which the top or ceiling plate B is bent at its outeredge portion, as shown at y s, forming a right-angle flange portion t, overlapping the edge of the perforated plate D. The bottom plate C being formed in a similar way, the two portions will constitute a frame, against which the panel portions of the prison are secured.

As has been hereinbefore stated, the essential feature of this invention consists in provi di ng a wrought-m etal perforated panel-plate. I would therefore not be limited to any particular construction or form of frame.

Having thus fully described the nature and obj ect of my invention, what I claim as new, and desire to secure by Letters Patent, is

l. In a prison, the combination, with upper and lower plates, as B and C, forming ceiling and floor portions, of a wrought-metal plate D, having perforations (l, forming side panels E, substantially as described, and for the purpose set forth.

2. In prisons, the combination,with the upper and lower metal plates B and C, forming ceiling and floor portions, of the wroughtmetal plates D, having perforations, as d, forming side and door panels, and an angle corner bar, by which said plates are secured together, for the purpose set forth.

3. In a prison, the combination, with the solid metal side, top, and bottom portions, as A, B, and C, of a side panel portion E, consisting of a wrought-metal plate having perforations, as d, punched or cut therein, throug'h which air and light may pass into the prison, substantially as described.

4. In a prison composed in part of solid metal plates or other suitable material, wrought-metal plate D, having a solid marginal portion, and perforations d, whereby air and light may be admitted into the prison, substantially as described.

5. In a prison, the combination, with a supporting-frame, of a wrought-metal side and panel having a solid marginal portion and perforations cnt or punched through `its ceutral portion, substantiallyas described, and for the purpose set forth.

G. A prison-door constructed of a wroughtmetal plate having series of perfor-ations, as d, substantially as described, and for the p u rpose set forth.

7 In the construction of a prison, a metal plate composed of alternatelayers of iron and steel, having series of perforations, substantially as described, and,for the purpose set forth.

In testimony whereof I have hereunto set my hand this lst day of August, A. D. 1889.
